 129
 130 wx.MediaCtrl is a class that allows a way to convieniently display
 131 various types of media, such as videos, audio files, natively through
 132 native codecs.  Several different formats of audio and video files are
 133 supported, but some formats may not be playable on all platforms or
 134 may require specific codecs to be installed.
 135
 136 <p>
 137 wx.MediaCtrl uses native backends to render media, for example on Windows
 138 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 139 QuickTime backend.
 140 <p>
 141 wx.MediaCtrl is not currently available on unix systems.
